SPECIFICATION forming part of Letters Patent No. 678,226, dated July 9, 1901.

Application filed November 2, 1900. Serial No. 35,241. (No model.)

To all whom it may concern:

Beit known that I, EDWARD CONLEY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Beating-Engine, of which the following is a full, clear, and exact description.

The invention relates to machines used for treating or reducing fibrous material to a finely-comminuted mass, as is required in the manufacture of paper or other analogous products.

The object of the invention is to provide a new and improved beating-engine arranged to insure a uniform straight wear on the knives of the beating-drum and revolving bed-roll and to allow the beating-drum to yield upon the passage of lumpy matter passing between said drum and said bed-roll, and thereby avoid injury to the knives.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in which similar characters of reference indicate cor-- responding parts in all the views.

Figure 1 is a plan view of the improvement. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged side elevation of one of the supporting-levers for the beating-drum and adjacent parts. Fig. 4: is an enlarged'plan view of the grinding-roll and the bed-roll with one set of knives, and Fig. 5 is a like view of a modified form of the same. V

In beating-engines as heretofore constructed and having a beating-drum and a revolving bed-roll both provided with knives set obliquely, for instance, as shown in the Letters Patent of the United States No. 407,641, granted to me on July 23, 1889, it has been found that when the engine is in use and the beatingdrum runs at a higher peripheral speed than the bed-roll then in a short time the knives on the beating-drum are wornconcave, while the knives on the revolving bedroll appear convex. This wear proves that uneven work is done by the machine, and

the wearing down of the knives as described makes repairs costly. In order to insure proper working of the machine and prevent this undesirable wear of the knives, it is necessary to set the knives parallel to each other and obliquely across the peripheries of the beating=dru m and bed-roll,but with the knives of the drum at a certain angle to the knives of the bed-roll, so that the individual knives of the beating-drum and bed-roll move obliquely across each other in their passage past one another to produce an oblique or shearing action. A positive relation exists between the angle at which the knives are set and the difference in the peripheral speed given to the beating-drum and the bed-roll, and I have found by practice that the peripheral speed of the bed-roll must be lower than that of the beating-drum, and the knives on the bed-roll are set obliquely to the periphery of the bed-roll at an angle less than the angle at which the knives on the beatingdrum are set. This arrangement applies both to the cylindrical beating-drums and bed-rolls shown in Fig. 4, as well as to the conical beat ing-drums and bed-rolls shown in Fig. 5.

In the machine shown inthe accompanying drawings the vat or tub Ais of usual constructionand provided with a mid-feather B, at one side of which are arranged a beatingdrum- 0 and a bed-roll D, having knives C and D on their peripheral surfaces, the

knives 0 being set obliquely on the peripheral face of the beating-drum and at an angle somewhat in excess of that at which the knives D are set obliquely on the face of the bed-roll D. (See Figs.,i and 5.) The knives C D are set at angles to each otherthat is, they converge-and the drum 0 is rotated with a higher peripheral speed than that given to the bed-roll D to insure proper beating of the stock in the vat or tub A. In the latter is arranged'the-usual backfall E, of

any approved construction, and over the drum 0 and bed-roll D is arranged a suitable cover F. The shaft H is provided with a pulley H, connected by belt with other machinery for imparting the desired rotary motion to the shaft H and its bed-roll D, and said shaft is journaled in suitable bearings H held stationary on the standards forming I part of the machine. The shaft G is also provided with a pulley G, connected by belt with other machinery for rotating the shaft G and the beating-drum O at the desired rate of speed, as above described. The shaft G is journaled in suitable bearings G carried on the upper ends of the vertical arms of bell-crank levers I, fulcrumed at I on suitable standards arranged outside of the vat or tub A, and the horizontal arms of the bellcrank levers I are recessed to receive nuts J, pressed on at top and bottom by springs J and J carried in the free ends of the horizontal arms of the bell-crank levers I, as is plainly indicated in the drawings. In the nuts J screw the screw-rods K, extending upwardly and journaled at their lower ends in suitable steps K, the upper ends of said screw-rods carrying worm-wheels L in mesh with worms L, arranged on a transverse shaft N, extending across the top of the bed A and jonrnaled in suitable bearings held on the outside of the tub. On one end of the shaft N is secured a hand-wheel N under the control of the operator to permit the latter to turn the shaft N and cause the worms L to simultaneously rotate the worm-wheels L on the screw-rods K to simultaneously screw the nuts J up ordown, according to the direction in which the hand-wheel N is turned. As the nuts J are connected by the springs J J with the bell-crank levers I, it is evident that a swinging motion is given to the levers to move the shafts G and the beating-drum 0 toward or from the bed-roll D, according to the direction in which the hand-wheel N is turned.

By the arrangement described the beatingdrum 0 can be readily adjusted relatively to the bed-roll so that any wear on the knives O or D can be compensated for to hold the knives in proper relation to each other and insure proper beating of the stock. By making the yielding connection between the nuts J and the bell-crank levers I it is evident that when lumpy matter or hard substances pass between the beating-drum and bed-roll then the former can readily yield to allow such matter to pass withoutdanger of breaking or otherwise injuring the knives O orD. As previously stated, the beating-drum and bed-roll may be made either cylindrical or conical, and in the latter case the base end of the beating-drum is adjacent to the side of the tub or vat, while the apex end is next to the mid-feather, and the apex end of the bed-roll is next to the side of the tub, while the base end is adjacent to the mid-feather.

bed-roll arranged as described the stock is thrown from the side of the tub or vat toa sidewise motion at the same time drawing the fibers out lengthwise.

The final result is 5 that the felting qualities of the stock are greatly improved.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A beating-engine having a revoluble beating-drum with peripheral knives, and a revoluble bed-roll having peripheral knives and rotating at a peripheral speed lower than that of the beating -drum, the peripheral knives on the drum being set parallel one to the other and obliquely to the periphery of the drum, and the knives on the bed-roll bein g set parallel one to the other and obliquely to the periphery of the roll at an angle less than the angle at which the knives on the beating-drum are set, as set forth.

2. A beating-engine having a revoluble beating-drum with peripheral knives, and a revoluble bed-roll having peripheral knives and rotating at a peripheral speed lower than that of the beating-drum, the knives on the beating-drum and the knives on the bed-roll converging, and the knives on the beatingdrum being set parallel one to the other and obliquely on the periphery of the drum, and the knives on the bed-roll being set parallel to one another and obliquely to the periphery of the bed-roll at an angle less than the angle at which the knives on the beating-drum are set, as set forth.
